Set Matplotlib Canvas Background Color: Quick Guide

To set the background color of a matplotlib canvas, you can create a new Figure object using plt.figure() function and set the background color. For example, you can use plt.figure(facecolor=’blue’) to set the canvas background color to blue.

Additionally, you can use plt.gca().set_facecolor(‘blue’) to set the background color of the current Axes object, or use plt.gca().set_axis_bgcolor(‘blue’) to set the background color of the coordinate axes of the current Axes object.

Here is an example code demonstrating how to set the background color of a matplotlib canvas:

import matplotlib.pyplot as plt

# 创建一个新的Figure对象，并设置背景颜色为蓝色
plt.figure(facecolor='blue')

# 绘制一个简单的图形
plt.plot([1, 2, 3, 4], [1, 4, 9, 16])

# 显示图形
plt.show()

After running the above code, you will see a matplotlib plot with a blue background.
